What was the Main Reason for the Extinction of the Mauritian

Question

What was the main reason for the extinction of the Mauritian Calvaria tree?
A) climate change
B) lack of germination
C) lack of blooms
D) the earlier extinction of dodos

Accepted Answer

The main reason for the extinction threat to the Mauritian Calvaria tree was the earlier extinction of dodos. The dodos used to eat the seeds of the Calvaria tree, and the passage through the dodo's digestive system was necessary for the seeds to germinate. After the dodos became extinct, the trees stopped regenerating because their seeds could no longer germinate without passing through a dodo's digestive system.
